I had this come up with my sale. The dealer thought they could put it on but come to find out it is too much to install everything after the fact. We worked it out with the dealer and ordered one from the factory with the tow kit. That's the only way to get it legally to the 3600 lbs. the dealer can't put in the electronics for the anti trailer sway and the adapter for the brake control. The rest of the pieces are just swapping out radiators and alternators. It's too expensive for them though.
